With the continuous attention of the state and industry to the prevention and control of geological disasters and the safety and security of engineering geological deformation,the vital role played by safety monitoring has been highlight-ed.Taking a domestic project as an example,the three-dimensional deformation monitoring is carried out based on the Beidou satellite navigation system.Combined with the one-month observation data of the Beidou reference station and the monitoring station,the quality of the Beidou observation data and the three-dimensional deformation of the monitoring sta-tion are comprehensively analyzed and evaluated with reference to the relevant accuracy indicators.The results show that the data quality of BDS observations is more stable than GPS.The performance of the two types of domestic receivers is basically the same.The internal coincidenceaccuracy plane of Beidou monitoring of 12 monitoring stations in the two re-gions is better than the elevation,and can meet the monitoring accuracy requirement of 3 mm,which can provide certain technical support for geological disaster prevention and engineering geological deformation monitoring.
